Well, in the first sentence, the verb is formed from “get.” This verb can be conjugated:

Present: I get

Preterite/past: I got

Present continuous: I am getting

Present perfect: I have gotten or (informally) I have got

Future: I will get

Future perfect: I will have gotten

Past continuous: I was getting

Past perfect: I had got

Future continuous: I will be getting

Present perfect continuous: I have been getting

Past perfect continuous: I had been getting

Future perfect continuous: I will have been getting

You might say, well, the preterite shows “I got;” so, what’s the problem? Well, “got” is past tense, as in “I got no money from Mary.” It might be better to choose a different verb and say, “I received no money from Mary.” But if you are trying to say that you’re broke and don’t have any money, “got” alone doesn’t suffice. You could say, “I have no money.” If you really want to be colloquial and informal, “I have got no money” has become a correct usage. It’s a case of picking the wrong verb or using the wrong tense.

In the second sentence, the verb is formed from “see.” This verb can be conjugated:

Present: I see

Preterite/past: I saw

Present continuous: I am seeing

Present perfect: I have seen

Future: I will see

Future perfect: I will have seen

Past continuous: I was seeing

Past perfect: I have seen

Future continuous: I will be seeing

Present perfect continuous: I have been seeing

Past perfect continuous: I had been seeing

Future perfect continuous: I will have been seeing

There’s no “I seen” as an option. You can say: I saw Game of Thrones on Sunday or I have seen Game of Thrones on Sunday. In the example “have” was dropped from the sentence. Often, we do that when we speak because we keep abbreviating. “I have seen Game of Thrones” becomes “I’ve seen Game of Thrones” becomes “I seen Game of Thrones.”
